Let’s start with the Yeti first. This article is based on the claims of “hominologist”* Igor Burtsev – in fact, it’s the third article about him thisyear – and even the Daily Mail doesn’t sound that convinced any more, judging by the fourth paragraph:

However, doubt has already been cast on the ‘find’ – as the team has no convincing photographic or DNA evidence. Their claim appears to be based on bent branches, a single unclear footprint and a small sample of grey ‘hair’, found in a cave.

Broken branches, a footprint, some hair and a “bed” (which was mysteriously free of hair) – that’s “finally proof the Yeti exists”? Let’s remember Wiener’s law for science journalism: if your article can be summarized as “no”, don’t write it.
